Uncertainty

Speaking of uncertainty, our life, from science perspective is a perfect laboratory. It has 100% probability of death and it has finite life span. And if use science perspective, it is a very rational decision of people to commit suicide, but yet the suicide rate is very low (1 for every 10,000). To have a balanced view, from science perspective it also very natural that a human will not perform suicide regardless the situation. The insight that life is a perfect laboratory has been identified by many parties from Thomas Hobbes, Copenhagen Interpretation to Walking Contradiction
